Greentech Lead America: Here’s the list of top 10 gas
saving technologies as identified by Total Car Score, a comprehensive
automotive ranking and comparison car website, to help car buyers select the
most energy-efficient model. The list also includes some popular models that
have implemented these technologies.
Start-Stop Engines: The start-stop technology improves
fuel efficiency in both hybrids and non-hybrids by shutting the engine down when
the vehicle is stopped. Seen on: BMW 3 Series, Kia Rio, Porsche Cayenne
Variable Valve Control: Variable valve control maximizes
fuel efficiency and performance by altering the opening and closing of an
engine’s valvetrain based on RPM and throttle input. Seen on: Mazda CX-5, SRT
Viper, Volkswagen Golf
Continuously Variable Transmissions (CVT): They have an
infinitely variable gear ratio that keeps an engine in its most fuel-efficient
operating zone across a wide range of speeds.
Seen on: Infiniti JX, Nissan Altima, Subaru Outback
Active Aerodynamics: This technology actively alters
their coefficient of drag according to vehicle speed and driving conditions.
Seen on: Cadillac ATS, Dodge Dart, Ford Escape
Lightweight Materials: Using high-strength steel, carbon
fiber and aluminum allows automakers to create lighter cars without sacrificing
safety and less weight means lower fuel consumption.
Seen on: Acura RDX, Hyundai Santa Fe, Scion FR-S
7+ Transmission Gears: This is a conventional automatic
transmission with seven or more gears designed to reduce fuel consumption by
keeping the engine operating at peak efficiency at any speed. Seen on: Bentley
Continental GT Speed, Dodge Ram, Mercedes-Benz S-Class
Direct Injection: This is an evolution of fuel injection,
which injects fuel directly into the combustion chamber in extremely precise
amounts to maximize fuel efficiency and reduce emissions.
Seen on: Buick Encore, Fiat 500, Lincoln MKZ.
Cylinder Deactivation: Shutting down one or more engine
cylinders when a car is coasting, or cruising under a light load, reduces fuel
consumption without impacting performance.
Seen on: Audi S8, Dodge Challenger, Lamborghini Aventador.
Plug-In Hybrids: Hybrids have evolved from charging their
battery packs while driving to charging their battery packs while plugged into
either a standard wall outlet or high voltage “quick charger.”
Seen on: Ford Fusion, Honda Accord, Toyota Prius
Mild/Light Hybrids: They use a smaller motor and battery
pack than traditional hybrids, and increase fuel efficiency with a minimal
increase in vehicle cost or weight. Seen on: Buick LaCrosse, Chevrolet Malibu,
Honda CR-Z
“Fuel efficient technology, and the impact it has on
EPA ratings for current and future models, is a critical component in the
design of today’s cars,” said Karl Brauer, editor in chief of Total Car
Score. “Gas prices and miles-per-gallon claims are now top consideration
points for new car shoppers when buying a car, playing a much
bigger role than they did 10 years ago. Given the average car on the road is 11
years old, many consumers will be encountering all-new fuel efficient
technology when they research their next vehicle purchase.”
